Roomate acting like a girlfriend

This is gonna be short, I'm walking and just want to vent before I go back home.

A bit of context, I'm 20M and she's 32F

I feel like I don't owe to tell my roomate where I will be at all times, when I'll be back. She got angry with me today (I assume by her passive aggressive response which was "k.") All because I was with my boyfriend after work and didn't tell her.

Do yall tell your roomates where you'll be everytime? This is my first roomate situation.
